How to find x and y using the triangle sum theorem

The sum of angles in triangle always add up to 180°.
Using this theory, we can first calculate x by listing out a algebraic formula.

92° + 85° + x = 180° (angle sum of triangle)
x = 3°

Now by using x = 3°, we can list another formula to calculate y.

100° + 3° + y = 180° (angle sum of triangle)
y = 77°

Therefore x is 3° and y is 77°.

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4

Iwould say d but i am not 100% positive
